The parameters for this multipart request

MultipartRequestWrapper

public MultipartRequestWrapper(HttpServletRequest request)

Method Details

setParameter

public void setParameter(String name,
 String value)

Sets a parameter for this request. The parameter is actually separate from the request parameters, but calling on the getParameter() methods of this class will work as if they weren't.

getParameter

public String getParameter(String name)

Attempts to get a parameter for this request. It first looks in the underlying HttpServletRequest object for the parameter, and if that doesn't exist it looks for the parameters retrieved from the multipart request

Specified by:

getParameter in interface ServletRequest

Overrides:

getParameter in class ServletRequestWrapper

getParameterNames

public Enumeration<String> getParameterNames()

Returns the names of the parameters for this request. The enumeration consists of the normal request parameter names plus the parameters read from the multipart request

Specified by:

getParameterNames in interface ServletRequest

Overrides:

getParameterNames in class ServletRequestWrapper

getParameterValues

public String[] getParameterValues(String name)

Returns the values of a parameter in this request. It first looks in the underlying HttpServletRequest object for the parameter, and if that doesn't exist it looks for the parameter retrieved from the multipart request.

Specified by:

getParameterValues in interface ServletRequest

Overrides:

getParameterValues in class ServletRequestWrapper

getParameterMap

public Map<String,String[]> getParameterMap()

Combines the parameters stored here with those in the underlying request. If paramater values in the underlying request take precedence over those stored here.

Specified by:

getParameterMap in interface ServletRequest

Overrides:

getParameterMap in class ServletRequestWrapper
